Question 10

10.

The graph of position vs. time is for a bike ride. Explain what is happening between 3.0 & 5.0 s during the ride by describing the position during that time, the velocity during that time, and the motion of the bike during that time. (3 pts)

Question 11

11.

A runner runs around a track that is 400 m around. She completes one lap in 75 seconds. What is her average speed? Show your work and include units in your answer for full credit. (4 pts.)

Question 12

12.

CER Question - A spectator claims that while the runner in the previous question does have an average speed, she doesn't have an average velocity. That is, her average velocity is zero. Make a claim, either agreeing or disagreeing with the spectator about the average velocity. Provide evidence and reasoning to support your reasoning from either the previous problem or your own experience. (4 pts.)
